Abstract (en)
A method of molding a foamed product is carried out by using a front and a rear mold (31, 32) for molding a front and a rear portion of the foamed product and a core (33) interposed between the front and rear molds. The method includes steps of pouring or spraying one of foaming stock solutions (41, 42) onto a molding surface of the one mold, arranging the core in the one mold and pouring or spraying the other foaming stock solution onto the core or a molding surface of the other mold. The front and rear molds are suitably closed at a moment of time 30-100% of a rise time of the foaming stock solution applied last. Thereafter the closed molds are maintained in a position where an angle of the closed molds relative to a horizontal plane is suitably within a range from 90 DEG to an angle more than 0 DEG . The front and rear molds are pivotally connected to each other with their one ends by means of a pivot shaft (35). The core is pivotally supported, with its one end by a shaft (37) arranged in parallel to the pivot shaft.
